    摘要: A TFT-PIN array substrate and an assembly structure for a flat-panel x-ray detector are provided to overcome the problem that the conventional scintillator substrate and TFT-PIN array substrate are neither penetrated by UV-light nor assembled by UV curable LOCA. The metal layer of the PIN photodiode of the TFT-PIN array substrate is perforated to have at least one hole, whereby UV-light can pass through the TFT-PIN array substrate to cure UV curable LOCA. Therefore, UV curable LOCA can be used as an adhesive layer in the assembly structure of a scintillator substrate and a TFT-PIN array substrate to promote the detective quantum efficiency and image quality of a flat-panel X-Ray detector.

    摘要: A low-cost neutron detector is formed on a substrate includes a sensor formed by an active material layer sandwiched between two electrodes, and a neutron capture layer formed in close proximity to (i.e., over and/or under) the sensor. The sensor active material layer includes a bulk heterojunction or bilayer structure that is formed by depositing particulate solutions incorporating at least one type of high atomic number nanoparticle using low-temperature (i.e., below 400° C.) solution processing techniques. The sensor electrode material and neutron capture material are similarly disposed in associated solutions (e.g., conductive inks) that are also deposited using low-temperature solution processing techniques, whereby the fabrication process can be carried out on low-cost flexible substrate material (e.g., PET) using high efficiency roll-to-roll production techniques. The neutron capture material is optionally patterned as an array of pillars, and the active layer materials are backfilled between the pillars.

    摘要: The invention is a photovoltaic device configured as a sandwiched structure comprising a bulk region between a pair of collecting electrodes. The bulk region comprises an electric-field inducing component and a photoactive component. The photoactive component is in electric contact with the collecting electrodes to provide a continuous conduction path for photo-generated charge carriers between the electrodes. The electric-field inducing component is adapted to provide a permanent electric field having high electric strength in the entire inter-electrode region, thereby inducing an electric field in the photoactive component. The electric-field inducing component does not participate in transport of the photo-generated charge carriers. The field inducing component can be comprised of a material that retains sustained polarization or a material that comprises and sustains a spatial distribution of electrical charges, or it can be comprised of both types of materials.

    摘要: High aspect ratio micromachined structures in semiconductors are used to improve power density in Betavoltaic cells by providing large surface areas in a small volume. A radioactive beta-emitting material may be placed within gaps between the structures to provide fuel for a cell. The pillars may be formed of SiC. In one embodiment, SiC pillars are formed of n-type SiC. P type dopant, such as boron is obtained by annealing a borosilicate glass boron source formed on the SiC. The glass is then removed. In further embodiments, a dopant may be implanted, coated by glass, and then annealed. The doping results in shallow planar junctions in SiC.
